Phosphodiesterase Type-5 Inhibitor Therapy in Sickle Cell People With Pulmonary Hypertension

Completed

Conditions studied: Pulmonary Hypertension, Sickle Cell Disease

In brief

Background: Sickle cell disease (SCD) is a common inherited blood disorder. Many people with SCD are at risk to get pulmonary hypertension (PH). PH means that the blood pressure in the blood vessels to the lungs is high, and is a serious disease and. Very few studies have looked at the success of treatments for PH in people with SCD. Researchers want to learn more about treating PH with a type of drug called phosphodiesterase type 5 inhibitors (PDE5-I). They will look at the records of people who have already joined other studies. Objective: To identify people who already joined NIH SCD protocols whose medical records should be reviewed. The review will look at the description of SCD patients with PH who have already taken PDE5-I and the outcomes for these people. Eligibility: Adults ages 18 and older with SCD and PH. They must have joined certain NIH studies and taken PDE5-I therapy for at least 16 weeks. Design: This study is a review of medical records. Researchers will collect data from databases of existing studies. They will identify people in those studies who have SCD and PH and took the study drug for at least 16 weeks. Researchers will review the full medical records of those people. From that review, researchers will find participants who meet the inclusion criteria. They will extract data from those records. Researchers will analyze the data. This includes results from heart and lung tests, imaging, and walking tests. It will also include results of a procedure called right heart catheterization. Demographic data and lab data will also be collected. Researchers will remove identifying information from the data, then share it in a database.
